watch_man

A small Rust CLI tool that inspects Linux TCP sockets from /proc and maps them to process IDs and names.

What it does

• Reads TCP socket entries from /proc/net/tcp
• Parses local port and socket state
• Builds an inode -> PID map from /proc/<pid>/fd
• Resolves process names from /proc/<pid>/comm
• Sorts results by port

Current status

This project currently parses and resolves data, but the output is still in a debug-oriented state:

• It prints raw parsed columns from /proc/net/tcp
• It prints the full inode/PID map
• main only prints a success/error message

So the core collection logic exists, but a final user-facing table/list output is not implemented yet.

Requirements

• Linux (uses /proc paths specific to Linux)
• Rust toolchain (recommended: latest stable)

Build and run

From the project root:

cargo run

Build release binary:

cargo build --release

Run tests (when added):

cargo test

Project layout

• src/main.rs: TCP parsing and process mapping logic
• Cargo.toml: package and dependency configuration

Notes

Dependencies currently include terminal/UI crates (ratatui, crossterm), but the present main.rs implementation is command-line and debug-print based.
